With upcoming changes, dtoc will output several files for different
of-platdata components.
Add a way to output all ava!ilable files at once ('all'), to the
appropriate directories, without needing to specify each one invidually.
This puts the commands in alphabetical order, so update the tests
accordingly.

"""Device tree to C tool
|
|
|
|
This tool converts a device tree binary file (.dtb) into two C files. The
|
|
indent is to allow a C program to access data from the device tree without
|
|
having to link against libfdt. By putting the data from the device tree into
|
|
C structures, normal C code can be used. This helps to reduce the size of the
|
|
compiled program.
|
|
|
|
Dtoc produces several output files - see OUTPUT_FILES in dtb_platdata.py
|
|
|
|
This tool is used in U-Boot to provide device tree data to SPL without
|
|
increasing the code size of SPL. This supports the CONFIG_SPL_OF_PLATDATA
|
|
options. For more information about the use of this options and tool please
|
|
see doc/driver-model/of-plat.rst
